IMPROVEMENT IN TRANSIENT-BOLTS FORVEHICLES;

The Schedule referred to in these Letters Patent and making part of thesame.

I, cm GUsrAr Hons'rnN, of Orebro, in the Kingdomof Sweden, have inventedcertain Improvements in Transient-Bolts for Carriages, of which thefollowing is a specification.

Nat-Me and Objects of my Invention.- The nature of my invention relatesto certain improvements on transient-bolts for carriages and similarvehicles for the purpose of strengthening and preserving saidtransient-bolts, as well as strengthening the timb'ersto which thetransient-bolts are attached in a manner as will now be fully shown anddescribed.

On' the drawing- Figure l is a ground plan; I

Figure 2'is a central longitudinal section overthe line X Y. taken onfig. 1; and

I Figure 3 is a front view of my invention.

= Similar letters refer to similar parts wherever they occur in thedrawing.-

a is theaxle-tree, to which is securely held the axle b, by means of thebolts-c a, as'shown.

c is what is generally termed the rocker, on the top of which thesprings c 0' rest in the usual manner. Aplate, e, is firmly secured tothe under side of the rocker c by means of the bolts f f projectingthrough the rocker and springs c c, and held in place by nuts or theirequivalents, as shown in .the diiierent view on thedrawing.

In the middle of the plate e is a projecting hub, i,

into which the transient-bolt d is screwed.

0n the upper side of the axle-tree a is another plate,

I; secured by means of the bolts hh projecting through said axle-treeand the axle b, and held in place by means of nuts on the under side ofthe axle b, as shown The plate t has, in the middle, a hub, 70, ofcircular form, made as a cup or receptacle for the hub '5 attached tothe plate a.

Between the lower end of the hub 13 and thebottom of the cup It I placea leather washer,-n, thoroughly greased, so as to prevent too great afriction on these i parts;

The transient-bolt d, after being firmly secured to the hub 'i, asdescribed, projects through the hub 70,

plate I, axle-tree a, and axle b, the whole being heldtogether by meansof ai lock-nut, m, below the axle b, as shown. I

The cross-bar 0 is mortised throughthe rocker c in a-usual manner, asshown in the drawing.

The advantages I gain over common transient-bolts is that'I do notproject my transient-bolt through the rocker c and the mortise for thecross-bar 0, thereby strengthening the connection of the rocker andcrossbar 0 materially.

I also obtain a strong and durable bearing of the rocker 0 onto theaxle-tree a with very little friction, as the .cup It forms a receptaclefor thelubricating material that is used.

Having thus fully described the construction and operation of myinvention, 4

I wish to secure by Letters Patent and claim The combination of thetransient-bolt d screwed into the hub 03, the metallic plates 0 and l,hub t, and receptacle k, and the anti-frictional washer n, whenall arecombined and arranged substantially as herein shown and described. OHARLG USTAF HOLSTEN.
